In order to facilitate packing the cotton, hay, o1

other material into the box by hand, before applyingr the power of the machine,I swing the head-block M ont in front of the posts AA, thereby leaving the upper part of the box entirely open and unobstructed.

From the foregoing description, it will be readily seen thatmy press possesses the following advantages among others:

First, extreme simplicity of construction. It has but few pieces, and those are such as can'be replaced by any common mechanic, as they require the use of no machinery in their manufacture Second, in the great amount of power developed, arising from the factthat I can use levers equaling in their combined length the entire height of the inachine, which I accomplish by applying `my roller or windlass to, the `junction of the two levers; an'd Third, its durability, from the fact that the plates or anges c and d prevent the levers from`being deected, or thrown out of line, as they are drawn toward posts A A, thus obviating any tendency to `Wrench and brealf them apart when they are pivoted to each other, and to the rest ofthe press.

Having now described myinvention,

lVhat I claim as new, and desire to secure by Letters Patent, is-' l. Mounting the roller F at the point of junction of.
